    Abstract: Methods for presenting symbolic expressions such as mathematical, scientific, or chemical expressions, formulas, or equations are performed by a computing device. One method includes: displaying a first portion of a symbolic expression within a first area of a display screen; while in a first state in which the first area is selected for aural presentation, aurally presenting first information related to the first portion of the symbolic expression; while in the first state, detecting particular user input; in response to detecting the particular user input, performing the steps of: transitioning from the first state to a second state in which a second area, of the display, is selected for aural presentation; determining second information associated with a second portion, of the symbolic expression, that is displayed within the second area; in response to determining the second information, aurally presenting the second information.

    Abstract: An electronic device can provide an interactive map with non-visual output, thereby making the map accessible to visually impaired users. The map can be based on a starting location defined based on a current location of the electronic device or on a location entered by the user. Nearby paths, nearby points of interest, or directions from the starting location to an ending location can be identified via audio output. Users can touch a screen of the electronic device in order to virtually explore a neighborhood. A user can be alerted when he is moving along or straying from a path, approaching an intersection or point of interest, or changing terrains. Thus, the user can familiarize himself with city-level spatial relationships without needing to physically explore unfamiliar surroundings.

    Abstract translation: 电子设备可以提供具有非视觉输出的交互式地图,从而使得地图可视化受损用户可访问。 地图可以基于基于电子设备的当前位置或由用户输入的位置定义的起始位置。 可以通过音频输出来识别附近的路径,附近的兴趣点或从起始位置到结束位置的方向。 用户可以触摸电子设备的屏幕,以便虚拟探索邻里。 当他正在沿着或偏离路径,接近交叉点或兴趣点或改变地形时,用户可以被警告。 因此,用户可以熟悉城市空间关系,而不需要物理探索陌生的环境。
